Operation This section will explain the function of each convenient control (Figure 2). To access the controls, flip open the control panel cover towards the bottom of the fireplace (Figure 1). Figure 1 Resetting the Temperature Cutoff Switch This unit is equipped with a thermostat which controls the temperature of the room by turning the heater on and off. The heater is protected with a safety device to prevent overheating. Should the heater overheat, an automatic cut out will turn the heater off and it will not come back on without being reset. It can be reset by switching the Main ON/OFF Switch to OFF and waiting five (5) minutes before switching the unit back on. CAUTION: If you need to continuously reset the heater, unplug the unit and call customer service. Please have your model and serial number ready when calling. Figure 2 F A B E C D Remote Control The fireplace is supplied with a radio frequency remote control. This remote control has a range of approximately 15.25 m, it does not have to be pointed at the fireplace and can pass through most obstacles (including walls). It is supplied with one of hundreds of independent frequencies to prevent interference with other units. The frequency designation is indicated on the back of the transmitter. A. Flame Action Control Turn the flame action control knob to adjust the flame speed to the desired level. B. Interior Light Control Turn the interior light control knob to increase or decrease the brightness of the interior light. C. LED Indicators Indicates the current function of the fireplace. D. Flame/Heat Selection Switch Toggles between flame effect, low and high heat settings. E. Heater Thermostat Control To adjust the temperature to your individual requirements, turn the thermostat control clockwise all the way to turn on the heater. When the room reaches the desired temperature, turn the thermostat knob counter clockwise until you hear a click. Leave in this position to maintain the room temperature at its setting. For additional heat, turn clockwise until you hear the click again and the heater will turn on. To turn the heater off, rotate the knob fully counter clockwise. F. Main ON/OFF Switch The Main ON/OFF Switch supplies power to all fireplace functions. Remote Control Initialization Follow steps 1 through 4 to initialization your fireplace for the first time. This procedure is also required every time there is a loss of power to the remote control in the fireplace (i.e. power failure, breaker tripped, main power switch is turned off). 1. Ensure that power is supplied to Figure 3 the intended electrical receptacle. 2. Locate manual controls (refer to Figure 2). 3. Plug in fireplace, first indicator light will flash (Figure 2C). 4. Press and hold the Flame/Heat Selection Switch (Figure 2D) for five (5) seconds ( position) UNTIL the second red indicator light flashes. 5. Press ON button located on the Battery Cover remote control transmitter (Figure 3). This will synchronize the remote control transmitter and receiver. Remote Control Usage The remote control operates the fireplace levels sequentially, flames only to flames and low heat, to flames and high heat. The level is increased every time the ON button on the transmitter is pressed. The fireplace can be turned off at any point by pressing the OFF button on the remote control transmitter. Level : The flame effect is turned on and the first red indicator light flashes momentarily. 3

Level : The flame effect remains on, the heater is activated to the low heat setting, and the first and second red indicator lights flash momentarily.
